Umusaruro winganda za erythritol ukoresha cyane cyane uburyo bwa fermentation ya mikorobe, aho kuvana mubihingwa bisanzwe. Ni ukubera ko erythritol ifite ibintu bike muri kamere, kandi gukuramo bitaziguye birahenze kandi bidakora neza. Ibikurikira nuburyo bwibanze ningingo za tekiniki zo gukora inganda za erythritol:

Uburyo bukuru bwo kubyaza umusaruro: Uburyo bwa fermentation ya Microbial
Guhitamo ubwoko bwa bagiteri

Ubwoko bwibanze: Umusemburo wa erythritol utanga umusaruro mwinshi (nka Moniliella pollinis, Yarrowia lipolytica) cyangwa ibumba (nka Trichosporonoides megachiliensis).
Gukoresha ingengabihe ya tekinoroji: Ikoranabuhanga rigezweho ryongerera isukari igipimo cy’isukari hamwe n’umuvuduko ukabije wa osmotic w’imiterere ya bagiteri binyuze mu guhindura geneti.
Gutunganya ibikoresho

Inkomoko ya karubone: Koresha glucose cyangwa sucrose igisubizo (hamwe nubushakashatsi bugera kuri 30-35%, ukarema ibidukikije bya osmotic kugirango uteze imbere synthesis ya erythritol).
Mbere yo kuvura: Ibikoresho bihendutse nka krahisi y'ibigori bigomba guhinduka muri glucose binyuze muri hydrolysis enzymatique (α - amylase + amylase).
Inzira yo gusembura

Oxygene yagenzuwe na fermentation: Kora fermentation yimbitse mubigega binini bya fermentation, kugenzura neza pH (5.0-6.0), ubushyuhe (28-34 ℃), hamwe na ogisijeni yashonze.
Umuvuduko ukabije wa osmotic: Mugihe cya glucose nyinshi, mikorobe ihindura glucose imwe muri erythritol kugirango iringanize umuvuduko wa osmotic selile.
Intambwe zingenzi zo gutandukana no kwezwa

Ibisobanuro bya tekiniki byintambwe
Kurungurura Sterilisation, microfiltration cyangwa centrifugation kugirango ikureho selile na bacteri nini
Decolorisation desalination ikora karubone adsorbs pigment, ion yoguhindura resin ikuraho imyunyu ngugu
Kwibanda kuri kristalisation vacuum evaporation yibanda kuri supersaturation → gukonjesha kristalisation (kugenzura imbuto no kugabanya ubukonje)
Kwumisha Centrifugal, gutandukanya centrifugal ya kristu → ibitanda byumye byumye kugirango ubone kristu yera ifite ubuziranenge burenze 99.5%
Kubaho bisanzwe no gukuramo igipimo gito (kitari inganda)
Nubwo umusaruro winganda ushingiye kuri fermentation, erythritol isanzwe ibaho muri:

Imbuto: inzabibu, amapera, garizi (ibirimo nka 0.005-0.1%)
Ibiryo bisembuye: isosi ya soya, kubera
Gukuramo uburyo bwo kugerageza (kubushakashatsi bwa siyanse gusa):
mermaid
Gukoporora Kode
igishushanyo LR
A [Icyitegererezo cyo Gusya] -> B [Gukuramo Amazi Ashyushye]
B -> C [Imvura igwa ya Ethanol polysaccharide]
C -> D [ion guhana chromatografiya yoza]
D -> E [HPLC itandukanya erythritol]
Ibibi: Umusaruro muke cyane (Kugereranya ibyiza nibindi bicuruzwa byinzoga
Ibiranga erythritol xylitol / sorbitol
Fermentation substrate glucose / sucrose hemicellulose hydrolyzate (xylose)
Ingorabahizi yo korohereza: Byoroshye korohereza (solubilité ya 37g / 100g kuri 25 ℃). Sorbitol ikeneye korohereza buhoro kugirango ikumire
Inzira ya metabolike: Umubiri wumuntu ntushobora guhinduranya (Iterambere ry'ikoranabuhanga
Gukoresha imyanda: Kugerageza gusimbuza glucose itunganijwe na lignocellulose hydrolyzate kugirango ugabanye ibiciro fatizo hejuru ya 30%.
Gukomeza fermentation ikomeza: bioreactor nshya ya membrane igera kumusaruro uhoraho, bigabanya ukwezi kwa fermentation kumasaha 48.
Icyatsi kibisi: Ultrasonic ifashwa na tekinoroji yo gutezimbere itezimbere ubuziranenge bwa kirisiti (> 99,9%) kandi igabanya gukoresha ingufu.
Umwanzuro
"Gukuramo" ya erythritol mubyukuri bivuga inzira yo gutandukanya fermentation yinganda, kandi kuvoma bisanzwe bifite ubusobanuro gusa. Ikoranabuhanga rigezweho rikoresha imiterere ya genetike, fermentation yibanze cyane, hamwe nubuhanga butandukanye bwo gutunganya kugirango habeho umusaruro uhendutse wa toni miriyoni kumwaka, byujuje ibyifuzo byibiribwa bya sukari. Niba hakenewe ibipimo byihariye cyangwa amakuru yipiganwa asabwa, izindi nkunga zishobora gutangwa.
